The Colorado Department of Health and Environment (CDPHE) Water Quality Control Division is developing an approach to manage nutrients in Colorado waters. The primary driver for this effort has been an Environmental Protection Agency (EPA) directive to reduce nutrients in waters under jurisdiction of the federal Clean Water Act (CWA). The Division's proposal to control the discharge of nutrients relies largely on a technology-based control regulation that would establish effluent limits for both total phosphorus (TP) and total inorganic nitrogen (TIN) for many domestic and some nondomestic wastewater treatment facilities that become subject to the control regulation will have to invest in capital improvements and ongoing operation and maintenance (O&M) costs.
The State of Colorado receives migrant education program (MEP) funding for which federal law mandates that the state identify and recruit all migrant students residing in Colorado who are eligible to receive services provided by the MEP. Identification and recruitment are critical activities because, the children who are most in need of program services are often those who are the most difficult to find.

This report summarizes the process of creating an earthquake public information program. The program is to inform the general public, including all ages, incomes and education levels, of any earthquake risks in Colorado as well as methods of preparation for an earthquake event
From the turn of the century through 2008, fewer Coloradans died of cardiovascular disease. Although fewer were dying of heart disease and stroke, more Coloradans were developing the risk factors that lead to cardiovascular disease. High blood pressure is pervasive, obesity rates have doubled and too few Coloradans get the nutritious food and physical activity needed to keep their hearts healthy. Research shows that social, economic and environmental factors have a significant impact on health outcomes.
This study is the evaluation of two thin bonded epoxy overlays. These two products were compared on the basis of physical properties, including mean texture depth, surface friction, bond strength, ability to stop chloride intrusion, and anti-icing properties, as well as traffic safety and cost. Both overlays worked as intended when they were initially applied on the bridge decks. Mean texture depth and friction testing have shown that they both provide a durable wearing surface with good traction.
